· JVASP-27786· NaTeF5

NaTeF5 (sodium tellurium pentafluoride) is an inorganic fluoride ceramic compound containing tellurium, belonging to the family of complex metal fluorides used in specialized optical and electrochemical applications. This material is primarily of research and development interest rather than established commodity production, with potential applications in solid-state ionic conductors, optical materials, and advanced electrolytes where its fluoride chemistry and tellurium coordination offer unique electrochemical or optical properties compared to conventional ceramics.
